Abstract:

Nanoparticles can cross cell boundaries or move from the lungs directly to the bloodstream and ultimately reach all organs in the body due to their unique features including small size, shape, high surface area, chemical characteristics, solubility and degree of agglomeration. Nanoparticles entering the body through the skin, air or different ways have shown toxic properties and harming human health. In areas such as cosmetics, textiles and food, nanostructured materials may be used under specific standards, as nanostructured materials may have toxic properties. Because of the risks posed by nanomaterials, important rules and the methods have been established for the use and storage of these materials. Developed countries have established and become members of international organizations for the safe use of nanomaterials. These organizations have established regulatory policies and standards for using of nanomaterials in the different fields. The countries comply with the standards established by these organizations and implement policies for the use of nanomaterials in this direction. It is crucial to use nanomaterials according to these regulatory policies for the environment and human health. This paper discusses the regulatory policies established and used for nanomaterials in various countries of the world and the organizations that make up these regulations. It is mentioned that these regulations and policies should be taken into consideration for the use of nanomaterials and that these rules should be followed.
